RELATED APPLICATIONS

The present application claims priority from U.S. Patent Application62/812,986 filed Mar. 2, 2019, titled “Fiber Management Enclosure withUniboot for a Fiber Optic Connector”, which is incorporated byreference.

BACKGROUND

The present disclosure relates generally to an enclosure or strainrelief boot for helping to ensure incoming optical fibers are positionednext to each other without tangling or damage during use.

The prevalence of the Internet has led to unprecedented growth incommunication networks. Consumer demand for service and increasedcompetition has caused network providers need to find ways to improvequality of service while reducing cost.

Certain solutions have included deployment of high-density interconnectpanels. High-density interconnect panels may be designed to consolidatethe increasing volume of interconnections necessary to support thefast-growing networks into a compacted form factor, thereby increasingquality of service and decreasing costs such as floor space and supportoverhead.

In communication networks, such as data centers and switching networks,numerous interconnections between mating connectors may be compactedinto high-density panels. Panel and connector producers may optimize forsuch high densities by shrinking the connector size and/or the spacingbetween adjacent connectors on the panel. However, in a high-densitypanel configuration, adjacent connectors and cable assemblies have a lotof incoming optical fibers that need to be organized with their fiberoptic connectors so when removed from an adapter or receptacle theincoming fibers do not become tangled and break.

SUMMARY

According to one aspect of the present disclosure, there is provided anoptical fiber flexible boot configured to hold a plural of opticalfibers. The flexible or resilient boot is one-piece and configured withindividual ports, slots or openings to secure the incoming plural ofoptical fibers from the fiber optic cable. The fiber optic cable may bea round cable with a plural of optical fiber and strength members or aflat cable or ribbon cable with a plural of optical fiber and strengthmembers. Strength members include flexible wire or aramid fibers. Thefibers are usually secured with about a crimp post that extends from adistal end or cable end of the fiber management enclosure.

In the present invention, the back body is molded as one-piece ortwo-piece including a cavity. The backbody is configured to accept thefiber management enclosure. The enclosure is received at a proximal endor open end of the back body. The distal end or cable end of the backbody has crimp ring post molded as part of the back body main body. Thecrimp ring post can accept a deformable metal ring. When the opticalfibers are passed through the passageway of the post, the strengthmembers are positioned about the outer dimension of the post. The metalring is crimped over the strength members. Alternatively, the post maybe treaded to accept a screw cap that can bind the strength membersbetween the inner threads of the screw cap and the threads of the post.Also, the cable jacket can be secured to post to improve pull-strengthof the fiber optic cable during use. During use, a user may pull on thefiber optic cable to remove the fiber optic connector bundle from theadapter instead of pulling on the back body. Pulling on the cableincreases stress on the optical fibers causing breaks or fracturesleading to light loss or optical signal loss called insertion loss.

The fiber management enclosure has a main body with outer dimensionsconfigured to be received and secured within the cavity of the backbody. The distal end has main passageway that receives the plural ofoptical fiber from the fiber optic cable. Each optical fiber is fedthrough or positioned in a channel that branches off or extends from theinput port for the optical fibers into one or more upper and lowerchannels. The upper channels then further branch off into lower channelsthat each secure one or more optical fibers in slots. To help ensure theoptical fibers are maintained within the channels, the back body furthercomprises retention slots sized to accept the optical fiber withoutfracturing or breaking the optical fiber, and hold the optical fiber inplace.

The fiber management enclosure replaces fiber optic connectors andcassette in a network system. A trunk line interconnects two networkportions interconnect with fiber optic connectors such as MPO connectoror multi-fiber push-on connector. The trunk line is a high capacityoptical transmission line.

FIG. 17A and FIG. 17B depict a network topology. FIG. 17A is a prior artnetwork connecting first network (58.1) with second network (58.2) withtrunk (50). Four-port transceiver (56.1) delivers optical signal andeach signal is delivered to fiber optic connector (57.1-57.8) from firstMPO connector (59.1). Each optical fiber (40) is consolidated within acavity of first cassette (51.1). The cavity holds the plural of opticalfiber from LC/DX fiber optic connectors (57.1-57.8). The optical fibersare laid in cassette body (51.1, 51.2), and spliced to second MPOconnector (59.2) that is in optical communication with trunk line (50).Third MPO connector (59.3) is configured to break out the plural ofoptical signals from trunk line (50) and then reconnect to acorresponding optical fiber connector (57.5-57.8). A second cassette(51.2) consolidates the optical fibers from the third MPO connector(59.3). The optical fibers (40) are spliced to a corresponding LC/DXfiber optic connector (57.5-57.9) are in optical communication withfourth MPO connector (59.4). The fourth MPO connector is in opticalcommunication with a second transceiver (56.2). Transceiver may be aPSM4, DR4 or SR4 configuration. Reading FIG. 17A from left to right,there are four MPO connectors, eight LC/DX fiber optic connectors andtwo cassettes. Optical fibers are loosely placed in the cassette cavity,which lead tangling and breakage of the optical fibers.

FIG. 17B depicts the present invention deploying managed fiber opticconnector assembly (100) with the fiber optic management enclosure (10)and back body (20) or integrated fiber optic management enclosure (60)deployed to interconnect the first network (58.1) and second network(58.2) along the trunk line (50). MPO connectors, LC/DX connectors andcassettes, of FIG. 17A, are replaced by connector (100) and a plural ofdata center connectors (65). All the connectors (65) are of the sametype helping to reduce inventory, and simplifying network install.Managed fiber optic connector (100) accepts the optical fibers from thetrunk line at a second managed fiber optic connector (100) operativelyconnected to the second network. As described above connector (100) hasoptic fiber management enclosure (10) formed as a two-piece assemblywith back body (20) or integrated enclosure (10) with back body (20)resulting in a one-piece, integrated fiber optic management assembly(60). The trunk line is a fiber optic cable with a plural of opticalfibers. The plural of optical fibers are provided by a fiber optic cableor by a plural of fiber optic connector (65) each operatively connectorto another fiber optic connector (65). A first transceiver (56.1) isoperatively connector to a plural of fiber optic connectors (65), whichare operatively connected to a second plural of opposing fiber opticconnectors (65). The second plural of fiber optic connectors (65) havetheir optical fiber guided by an upper channel and a lower channel or aunitary channel formed as part of fiber optic management enclosure (10)or integrated fiber optic management assembly (60) respectively, whichcan be used to form managed fiber optic connector (100.1, 100.2). Trunkline (50) interconnects managed fiber optic connector (100.1) andmanaged fiber optic connector (100.2) to form an optical communicationpathway trunk line (50) to interconnect the first network (58.1) withthe second network (58.2).

Still referring to FIG. 17B, the removal of cassettes (51.1, 51.2) andplural of MPO connectors (59.1-59.4) simplifies the network topology andconstruction. The use of fiber optic connectors (65) allows the user tosplice and connector only one type of connector not two as in FIG. 17A,the prior art network, using MPO connector (59) and the LC/DX connectors(57). Next, cassette (51) does not provide channels, as in the presentinvention, that guide, retain and route the optical fibers from a firstside of the cassette to the second side of the cassette therebyincreasing optical fiber breakage and damage due to tangling of opticalfiber together. And if an optical fiber has a latent breakage that at alater date manifests itself, it is much easier for the user to trace thedamaged fiber and remove it from the channel (12, 13) than from atangled group of 100's of optical fibers stuffed into a cavity of acassette.

Typical prior art, such as U.S. Pat. No. 6,496,648 titled Optical FiberCassette, to Andersen assigned to Lucent Technologies, Inc., has aplural of spool walls to wrap optical fiber. The present inventiondiffers in channels one after another continually branch of the pluralof optical fiber until the needed optical fiber are positioned atferrule of the optical fiber connector or optic fiber assembly.

With respect to the use of substantially anyplural and/or singular terms herein, those having skill in the art cantranslate from the plural to the singular and/or from the singular tothe plural as is appropriate to the context and/or application. Thevarious singular/plural permutations may be expressly set forth hereinfor sake of clarity.

It will be understood by those within the art that, in general, termsused herein, and especially in the appended claims (for example, bodiesof the appended claims) are generally intended as “open” terms (forexample, the term “including” should be interpreted as “including butnot limited to,” the term “having” should be interpreted as “having atleast,” the term “includes” should be interpreted as “includes but isnot limited to,” et cetera). While various compositions, methods, anddevices are described in terms of “comprising” various components orsteps (interpreted as meaning “including, but not limited to”), thecompositions, methods, and devices can also “consist essentially of” or“consist of” the various components and steps, and such terminologyshould be interpreted as defining essentially closed-member groups. Itwill be further understood by those within the art that if a specificnumber of an introduced claim recitation is intended, such an intentwill be explicitly recited in the claim, and in the absence of suchrecitation no such intent is present. For example, as an aid tounderstanding, the following appended claims may contain usage of theintroductory phrases “at least one” and “one or more” to introduce claimrecitations. However, the use of such phrases should not be construed toimply that the introduction of a claim recitation by the indefinitearticles “a” or “an” limits any particular claim containing suchintroduced claim recitation to embodiments containing only one suchrecitation, even when the same claim includes the introductory phrases“one or more” or “at least one” and indefinite articles such as “a” or“an” (for example, “a” and/or “an” should be interpreted to mean “atleast one” or “one or more”); the same holds true for the use ofdefinite articles used to introduce claim recitations. In addition, evenif a specific number of an introduced claim recitation is explicitlyrecited, those skilled in the art will recognize that such recitationshould be interpreted to mean at least the recited number (for example,the bare recitation of “two recitations,” without other modifiers, meansat least two recitations, or two or more recitations). Furthermore, inthose instances where a convention analogous to “at least one of A, B,and C, et cetera” is used, in general such a construction is intended inthe sense one having skill in the art would understand the convention(for example, “a system having at least one of A, B, and C” wouldinclude but not be limited to systems that have A alone, B alone, Calone, A and B together, A and C together, B and C together, and/or A,B, and C together, et cetera). In those instances where a conventionanalogous to “at least one of A, B, or C, et cetera” is used, in generalsuch a construction is intended in the sense one having skill in the artwould understand the convention (for example, “a system having at leastone of A, B, or C” would include but not be limited to systems that haveA alone, B alone, C alone, A and B together, A and C together, B and Ctogether, and/or A, B, and C together, et cetera). It will be furtherunderstood by those within the art that virtually any disjunctive wordand/or phrase presenting two or more alternative terms, whether in thedescription, claims, or drawings, should be understood to contemplatethe possibilities of including one of the terms, either of the terms, orboth terms. For example, the phrase “A or B” will be understood toinclude the possibilities of “A” or “B” or “A and B.”
